Features

Compact series
The compact build allows direct mounting on the damper shaft.
Plug-in terminal blocks
Plug-in terminal blocks for easy exchange of room automation stations.
Integrated actuator
The actuator gear base is integrated into the housing of the actuating XDR. It supports dampers with up to 10 Nm torque.

Use

The Design Room Automation offers the highest level of flexibility for energy- optimized solutions while satisfying requirements for temperature control, ventilation, and comfort using standard tools and established workflows.
Pre-installed application types
Variable (VAV) and constant air volume flow control

Functions

The selected application and its parameters as well as input and output configuration determine the room automation station’s functionality. A detailed description of functionality is available in the ABT (Automation Building Tool) online help.
Communication

• 2-port Ethernet switch for cost-effective cabling via line topology Note: DXR1 supports cabling based on daisy chain topology. The max. the number is 20 devices and in the event of a failed automation station, all other stations are no longer reachable. DXR1 can be cabled as ring topology if higher reliability is required. This requires support for layer 2 switches RSTP (Rapid Spanning Tree Protocol) as well as SNMP monitoring and that any loss of the superposed system is reported. In the event of a fault, switching the communication paths can take between 10 and 30 seconds. DXR1 routes the RSTP protocol for the switches. It does not actually process the RSTP protocol. Further information can be found in the Application Guide for BACnet Networks in Building Automation (A6V11159798).
• USB connection for service and commissioning and firmware download

Notes
Security

| CAUTION
---|---
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property damage.
● Observe national provisions and comply with the appropriate safety regulations.
● Use only properly trained technicians for mounting, commissioning, and servicing.

Engineering
Identification
Each device has a unique serial number to ensure efficient commissioning. It is provided on the adhesive barcode reader. The serial number can be read directly into the engineering tool using a barcode reader.
Wiring
Wiring must be sufficiently insulated to the available rated voltage. The sizing and fusing of the wiring depend on the connected load.

Mounting

The automation station is mounted directly on a damper shaft.
